I'm tired to repeat the same things for people not able to connect their info with the reality.
a) The fact that Kim Mc Donald, from some people of Athletics, was under suspicion of giving some product enhancing performances, doesn't means that is not true he was the first coach introducing high intensity training of "stamina" (following the system that produced the best runners in UK), before not used by Kenyans. So, since I'm a coach studying methodology of training (and in this role I'm a lecturer of IAAF having courses for elite coaches, also in Africa), this is a FACT that changed drastically the system of training. Under this point of view, this SPECIFIC training can give advantages of more than 3" in a competition like 1500m / Mile.
I cannot say that NOBODY took EPO or something similar, if I don't know. I can say, for example, that the WR holder of steeple (Shaheen was my athlete) NEVER USED ANY SUPPORT (ALSO LEGAL, like Vitamins) in his life, and beated the record in the period you consider under doping. You can believe or not believe, but this is the truth, and I think to know the truth, about my athletes, better than you.
b) The fact that Kim McDonald went in touch with Dieter Hogen is true, but the reason is clearly explained in your same post. Kim, as manager, understanding that the future (economically speaking) could be shining for Marathon only, asked to a specialist of this event to coach the athletes of the management, showing attitude for the distance. Under this point of view, it's not important if Dieter used some substance for enhancing performances (I know Dieter, and I'm sure that the Dieter coaching Kenyans never used some drug, of course I cannot know what he did during the period of East Germany). This because, IN ANY CASE, HE NEVER COACHED THE ATHLETES OF TRACK. This means that your info is not connected with the argument we are speaking about.
c) I never was in touch with Kim McDonald, but I respect him very much, expecially for the organisation he was able to give to the most part of Kenyan runners. Under this point of view, I recognize that Kim (for track) and Gabriele Rosa (for Marathon) were the first managers able to create an organisation, before not existing in Kenya. This is the main reason because in that period the performances became very much better. Don't do the mistake to connect the results with the training system only. In 1999 I was reponsible in Eldoret, for IAAF, of a stage of 20 days with all the African Countries, for athletes officially "Youth". It was the first time I met Dorcus Inzikuru (after training with me), and many top athletes of the next years (Gebremariam and Defar for Ethiopia, Ezekiel Kemboi and Viola Kibiwott for Kenya, Kifle for Eritrea, Fabiano Joseph for Tanzania, among others). Each Country had to send 4 athlets (2 boys and 2 girls) and 2 coaches. I prepared the full program of training, after dividing all the athletes (more than 60) in 6 groups : short distances (800/1500), middle (5000/10000) and long (who could show attitude for becoming a HM runner in short time), this both for males and females. I divided in 6 groups the coaches, too. Every group of coaches had to follow one group of athletes in their morning training, in the afternoon there was the discussion about the reasons of training. The next day, the group of coaches had to change the group of athletes. So, at the end of the period, all the coaches had some experience about every distance. Now, many of those coaches are the responsible in their Country.
In any case, I remember that there were 2 athletes for 800m (one from Benin, one from Malawi) really strong. They ran the heats of Kenyan National Champs (the young runners were allowed to run the heats as guests) in 1'46", aand this was the last competition of their career, because, when they went back home, Federation of Benin and Malawi didn't exist....
So, if you know the African reality, you understand HOW MUCH IMPORTANT WAS TO CREATE THE FIRST LEVEL OF ORGANISATION.
What disturbs me is the fact that a lot of people don't knowing everything (or very little) about Africa and African life, want to speak, starting from wrong ideas. Athletics (and, generally, sport) is something connected with the normal life, is not an isle where you can live without the problems of the other persons. You cant speak about African athletes if you don't know the African life, the normal problems they have (in the last month, I had 4 athletes losing a daughter 4 years old, or a brother 16y old, or their mom, or the sister of the wife of my collaborator Joseph Cheromei, waiting on the road for a matato, and killed by a car thrown 15 meters ahead by a lorry running very fast downhill without brakes), the sicknesses, the disturbs of people in their village, and every other type of problems, different from what happens in our society.
I don't want to justify their mistakes. I try to teach them what is correct, and what is not correct in the life. I try to teach what is the RESPECT for other people. But I understand WHY, many times, they have a wrong behavior (looking thru our parameters) that for them is not important. For example, about the problem of AGE.
One time, in Ethiopia, I asked to an athlete : "But, really, how old are you ?". He answered me : "My mom told me I'm born together with that tree". "Ok, and how old is that tree ?". "Like me".
In a Continent where the idea of TIME is something new (for example, it's very difficult to find some Kenyan respecting an appointment : we speak about "Kenyan Time" for considering a delay of 2 hours as normal), where the names of the persons have referement with THE PERIOD OF THE DAY YOU BORN (when goats goes out of their house, when sheeps come back, when the sun rises, when darkness arrives, etc...), but nobody knows the day, the month and in many cases the year of their birth, you understand that the official date of birth is something not important for their mentality.
For the most part of the athletes, what is important is to have the opportunity to compete in an international event. So, for their mind, to cut sometimes 5 years or more in their real age for running Youth or Junior Champs (that is normal), is the same thing of the girls, the most part of time ADDING 2 years in their real age, because, being only 14, they cannot run in Junior Team in WCCCh and cant have their first passport. To cut, or to add, is only a reason for surviving. Of course I cannot agree, but in the most part of the case there is not a really "will" to cheat, but only to find the system for having some opportunity.
I stay about 6-7 months per year in Kenya, and I learnt many things from them. I hope they were able to learn something from me, too. But, knowing their problems, their families, their children, day after day I felt in my heart growing a feeling with this people, with their pride and their mistakes, with their qualities and their bad behavior. When you see babies of 3-6 years running barefoot and dirty in the dust, laughing, happy with nothing ; when they come to you because, looking at a mzungu, in any case they see something different ; when you see what is the real INNOCENCE of the life, YOU CANT HAVE THE SAME SUSPICION YOU HAVE, AND YOU HAVE IN YOUR HEART THE FEELING TO DO SOMETHING FOR THIS PEOPLE.
This is the reason because I love Africa, and I try to teach them what I know, about the life in the World. And I don't care what people like you think, because I'm in peace with myself when I'm able to give some reason for smiling to this people, respecting moral values, that is the first point of my teachment.
But may be your heart is no more able to feel something like this. In this case, you are a poor and unlucky person, and I fell pity for your life.
